PUMP.

application led September il, 1818. erial Ee. 323,678.

pumps, and more especially to those having multiple cylinders with solid reciprocating pistons, and the object et the same is to produce an improved pump wherein the dow of liquid wil be constant, when the device is in operation.

Another object of this invention is the production of a pump having a plurality of cylinders and operatmg mechanisms whereby the piston in each cylinder is simultanelt ously drawing liquid into one end of the.

cyhnder while discharging liquidfrom the other end thereof, thus causin a constant dow of liquid from each cylin er when the pumpisin use. 1

@ther objects will appear in the following specification and claims. l in the drawings,

Figure 1 is a side elevationl and Figure 2 is a plan view of this pump, each partly in section. n

Figures 3 and 4 are cross sections on the line 3-3 and 4-4 respectively of Figurel. Figure 5 is a horizontal section through til inlet end of one cylinder on an. enlarged s e,

`Figure 6 is a vertical upper endof a well Figure 7 a cross of Figure 6.

By referring lto the drawing it willl be seen that 1 designates a well casing and, 2 the barrel therein leading down intothe water or other liquid to be raised. This barrel 2 extends a relatively short'distance above the end of the wall casing 1 and has its end threaded. nipple 3 having thethreaded ange 3 is mounted upon the threaded end of the barrel -2 as best shown in Figure 6. A valve seat 50 is carried in the nipple and has the guide 51 situated below the seat itself so as to form an eye to receive the stem 53 of the lvallvel' Athsdpringl is l'ovided for normally o lng 1s upwar y openmg valve 52h13 closed position. 4A pipe 41eads section through the casing, and section on the line 7-7 u' ircmtsvlvetoaT-coup 5 w enceiiis branch@- at 6 and 6' anigacli ders 8, it should branch leads through a valve '7 and 7 respectivelyA and into the inlet end of cylinders 8 and 8 mounted on a frame work 9 and as seen in Figure 2, there are preferably two such cylinders. l

The pipe 30 leads from le-joint 5 as shown in Fi re 2 and is connected by a T-joint 30 with said short pipe 31 to the check valve 7". Elbows 31' lead from the check valve 7" and lcommunicate with the interior of the lower end of the cylinders 8 through the cylinder heads 32. v Wit-hin each cylinder is a solid reciprocating piston 10, whose rod 11 leads out through the cylinder head thereof and connects with a block 12 slidably mounted in a ide 13 supported by a cross head 14. The locks in urn are connected by pitman rods 15 with cranks 16 at opposite ends of a shaft 17 and,

the shaft is rotated in any appropriate man- `ner as by a belt 18 passmg around a pulley 19 which is fast on the shaft between its bearings. For this reason the pistons are reciprocated simultaneously and oppositely Vwithin the cylinders.

I The flow or delivery pipe 24 is connected "with a T-coupling -25 and branched as at 26 and eachbranch 26 is connected with a T- joint 33. Short pipes 34 lead from these T- -jolnts 33 and are connected to the check valves 27 as shown in Figures' 2 and 5. It should further lie-noted that short pipes 35 also 'lead from the i"jointss 33 and are connected by elbows 36 to, the elongated pipes 37. Elbows 38 are carried by the opposite ends of the pipes 37 and are connected to the check valves 39 from -which extend elbows 40 communicating with the inner vrear ends of the cylinders 8 through the cylinder heads 32.

pistonslO are reciprocated within the cylinhe understood that there 'es When the device isin operation and vthe will be a continuous dow of liquid from each v cylinder. 'For the purpose of ex lanation,v attention is invited to Figure 2 w erein an arrow is disclosed indicating the direction of movement of one of the pistons. As this piston moves toward the right end of the cylinder it will be .seen that liquid within this end of the cylinder will be forcedtherefrom passing through check valves 27, short pipes 36, T-joints 33 branch 34, T-joint25- and thence through delivery pipe 24. At 'the same time this advanceof the piston causesliquid to be drawn from the barrel through the valve 3 to the T-joint 5 and thence through .the pipe 30 and T-joint 30 to and through the T-joint 7 and elbow 21 into the op osite or rear end or the cylinder.

As t is piston starts on its return stroke, it is obvious that the liquid within theleft end of the cylinder 8 will pass therefrom through elbow 40, check valve 39 and elbow 38 through pipe 37 and elbow 3G and thence through short pipe 35 elbow 33 and branch 26 and then to and through the delivery pipe 24. As this action is taking place it is obvious that the flow of liquid from T- 'oint 5 will pass through branch 6 and valve into the'ri ht end of cylinder 8. Although only t e operation of one cylinder has been set forth, it is to be understood that the operation of the other cylinder is exactly the same with the exception that as the one cylinder moves in one direction the remaining cylinder is moving in the opposite direction, although it is not absolutely necessary to have this particular form of operation, for irrespective of whether or not the cylinder is moved in unison and in the same direction or in opposite directions liquid will be drawn into the end of each cylinder and discharged from the opposite end thereof continuously, according to the direction of movement of the piston.

Therefore, it will be seen that a very edicient pump mechanism has ,been provided wherein each cylinder will produce a continuous pumping action drawing water into one end and ejecting water from the opposite end thereof and then drawing water into the end from which water has been ejected and forcing water from the end wherein. it has just been drawn. rangement of the pipes, lV-joints, elbows and valves is such as to allow a single feed to provide a feed for each end of the cylinder, while the arrangement also allows water to be ejected from each end of each cylinder and finally directed into a single delivery pipe, it being obvious that as the water of the several pipes is finally passed into a single pipe, 1t will driven therethrough at a. vry high pressure for any purpose desire The ar- Leashes In the present illustration of my invention it is presumed that the pumping cylinders are within the theoretical suction distance froml the level in the well, or that the inherent gas pressure in the well will force the liquid in the well to a point wheregit mav be taken up by the pump.

The foregoing description and the draw ings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that l may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is 1. rlhe combination with a pair of cylinders, solid pistons therein, and mechanism for reciprocating said pistons simultaneously and oppositely, of a well casing, a barrel therein extending a relatively short distance above the well casing and having its upper end threaded, a nipple mounted upon the threaded end of the barrel, a valve seat situated in said nipple and on the end of the barrel, an upward y opening check valve situated within the nipple, a pipe leading from the nipple and branched into the heads of the two c linders, inwardly opening check valves within said branches and How pipes opening from said heads and containing upwardy opening check valves.

2. n combination, a wall casing, a barrel therein extending a relatively short distance above the wall casing and havin its upper end threaded, anipple mounte Lupon the threaded end of the barrel, a valve seat situated in said nipple and on the end of the barrel, an upwardly opening check valve situated within the nipple, a pipe leading from the nipple and pumping mechanism communicating with said p1 e.
